FRT-TS-C Transfer bias front side setting value (C)
[When used]
An image failure occurs depending on the type or condition of the paper AND the problem cannot be eliminated by performing special printing
process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
- Increase the setting value. (Effective for toner scatter/dotted image)
- Decrease the setting value. (Effective for white dots/white flower patches/image with high granularity in halftone mode)
Setting range: -30 to 40 (Unit: 50V)
- It is preferable to enter values in the condition of "M <= C <= Y <= K".
[Factory setting value/Value after RAM clearing: 0]
FRT-TS-K Transfer bias front side setting value (Bk)
[When used]
An image failure occurs depending on the type or condition of the paper AND the problem cannot be eliminated by performing special printing
process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
- Increase the setting value. (Effective for toner scatter/dotted image)
- Decrease the setting value. (Effective for white dots/white flower patches/image with high granularity in halftone mode)
Setting range: -30 to 40 (Unit: 50V)
- It is preferable to enter values in the condition of "M <= C <= Y <= K".

BCK-TR-Y Transfer bias backside setting value (Y)
[When used]
An image failure occurs depending on the type or condition of the paper AND the problem cannot be eliminated by performing special printing
process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.

process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
- Increase the setting value. (Effective for toner scatter/dotted image)
- Decrease the setting value. (Effective for white dots/white flower patches/image with high granularity in halftone mode)
Setting range: -30 to 40 (Unit: 50V)
- It is preferable to enter values in the condition of "M <= C <= Y <= K".

PGR-YMCK Setting value of transfer bias between sheets (Y, M, C, Bk)
[When used]
The density of the entire area of 70 to 80mm from the leading edge of the sheet is low/high, or there are an infinite number of white or black spots in
an image when the entire print is halftone, etc.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
- Increase the setting value. (Effective for thin density in the area 70 to 80mm from the leading edge)
- Decrease the setting value. (Effective for high density in the area 70 to 80mm from the leading edge)
Setting range: -20 to 50 (Unit: 50V)

[When used]
An image failure occurs depending on the type or condition of the paper AND the problem cannot be eliminated by performing special printing
process.
[Adjustment method]
- The problem may be eliminated by changing the setting value.
Setting range: -20 to 20 (Unit: 100V)
